A fundamental assumption regarding spoken language is that the relationship between sound and meaning is essentially arbitrary. The present investigation questioned this arbitrariness assumption by examining the influence of potential non-arbitrary mappings between sound and meaning on word learning in adults. Native English-speaking monolinguals learned meanings for Japanese words in a vocabulary-learning task. Spoken Japanese words were paired with English meanings that: (1) matched the actual meaning of the Japanese word (e.g., “hayai” paired with fast); (2) were antonyms for the actual meaning (e.g., “hayai” paired with slow); or (3) were randomly selected from the set of antonyms (e.g., “hayai” paired with blunt). The results showed that participants learned the actual English equivalents and antonyms for Japanese words more accurately and responded faster than when learning randomly paired meanings. These findings suggest that natural languages contain non-arbitrary links between sound structure and meaning and further, that learners are sensitive to these non-arbitrary relationships within spoken language. 相似文献

Two experiments investigated the release from PI following a shift in mode of presentation of the study words. In each experiment, the interpolated task required processing of both auditory (A) and visual (V) information. The results were the same with mixed lists (Experiment I) and with independent groups (Experiment II): A release from PI was obtained following an A to V shift but not following a V to A shift. It was concluded that the mixed-modality filler task has functional characteristics very similar to those of an A filler and that the filler task influences the memory code for study items. 相似文献

Da Vinci stereopsis is defined as apparent depth seen in a monocular object laterally adjacent to a binocular surface in a position consistent with its occlusion by the other eye. It is widely regarded as a new form of quantitative stereopsis because the depth seen is quantitatively related to the lateral separation of the monocular element and the binocular surface (Nakayama and Shimojo 1990 Vision Research 30 1811-1825). This can be predicted on the basis that the more separated the monocular element is from the surface the greater its minimum depth behind the surface would have to be to account for its monocular occlusion. Supporting evidence, however, has used narrow bars as the monocular elements, raising the possibility that quantitative depth as a function of separation could be attributable to Panum's limiting case (double fusion) rather than to a new form of stereopsis. We compared the depth performance of monocular objects fusible with the edge of the surface in the contralateral eye (lines) and non-fusible objects (disks) and found that, although the fusible objects showed highly quantitative depth, the disks did not, appearing behind the surface to the same degree at all separations from it. These findings indicate that, although there is a crude sense of depth for discrete monocular objects placed in a valid position for uniocular occlusion, depth is not quantitative. They also indicate that Panum's limiting case is not, as has sometimes been claimed, itself a case of da Vinci stereopsis since fusibility is a critical factor for seeing quantitative depth in discrete monocular objects relative to a binocular surface. 相似文献

Three tests investigated how the geometric relation between object/landmarks and goals influenced spatial choice behavior
in rats. Two groups searched for hidden food in an object-filled circular arena containing 24 small poles. For the “Proximal”
group, four distinct objects in a square configuration were placed close to four baited poles. For the “Distal” group, the
identical configuration of objects was rotated 45° relative to the poles containing the hidden food. The Proximal group learned
to locate the baited poles more quickly than the Distal group. Tests with removed and rearranged landmarks indicated that the two groups learned to use the objects differently. The results suggested that close proximity
of objects to goals encouraged their use as beacons, while greater distance of objects from goals resulted in the global encoding
of the geometric properties of the arena and the use of the objects as landmarks.

Involving parents in child sexual abuse prevention programs 总被引:2,自引:0,他引:2

Conclusion The importance of involving parents in child sexual abuse prevention programs has been given much lip-service by prevention educators, but relatively little time, energy or resources in reality. This seems short-sighted at best, if the goal of these programs is truly prevention as they purport. Although the results of this study may have limited generalizability because of its sample size and its highly educated respondents, it is the first study to compare the knowledge of attending versus nonattending parents of a typical one-shot parent workshop. The results indicated that the parents as a whole were fairly well versed in the facts of sexual abuse, although as in previous studies, they did not extend the statistics on sexual abuse to their own children. However, probably the most important results were the enthusiastic responses for parent programs and involvement but in different formats, at different times, and in different environments than the current typical PTO evening, one-time meeting. Clearly child sexual abuse prevention programs should experiment with innovative ways to reach parents. If prevention programs can involve a small minority of motivated parents as they seem to be able to do, then together these parents and the educators may be able to develop methods and resources to involve the large majority of currently uninvolved parents. Such an integrated and involving community approach to the prevention of child sexual abuse seems necessary if the goal of prevention is ever going to be reached. 相似文献

The information transmitted in absolute identification quickly reaches its upper limit as the number of (one-dimensional) signals, and their range, is increased. Several explanations have been given of this phenomenon, but all are ad hoc in one way or another. Here we present a ‘memory’ or ‘rehearsal’ interpretation. The basic (psychological) representation of each signal in an absolute identification experiment is assumed to be quite accurate, and independent of the other stimuli used in the experiment. However, the identification of the stimulus presented on a particular trial is relative to a ‘frame’ (usually the range of stimuli in that experiment) that the subject must ‘rehearse’ using a fixed capacity rehearsal system. In special cases, this model reduces to earlier suggestions, but its general motivation seems somewhat less ad hoc than that of earlier ideas, and it is also easily applied to the absolute identification of multivariate signals and to magnitude estimation. 相似文献
